@RestController 
@RequestMapping(value = Constants.COMPANY, produces = MediaType.APPLICATION_JSON_VALUE) 
public class CompanyController { 
    @Autowired 
    private CompanyService companyService; 

@RequestMapping(method = RequestMethod.GET) 
public ResponseEntity find(@ModelAttribute CompanyDto request, @Valid @ModelAttribute PageableRequestModel pageRequest) { 
    final Page<CompanyDto> dtoPg = companyService.find(request, pageRequest.getPageable()); 
    return new ResponseEntity(PagedResponseDto.of(dtoPg), HttpStatus.OK); 
} 
} 

dies ist mein Controller-Test:

@Test 
    public void testListAll() throws Exception {  
     mockMvc.perform(MockMvcRequestBuilders.get(COMPANY)) 
     .andExpect(MockMvcResultMatchers.status().isOk()); 
    }

Answer 2

Es scheint, dass der Paging-Wert, den Sie an die Methode PagedResponseDto.of (...) übergeben, nicht gültig ist.

Dieses von der letzten Zeile des Codes kommt in dem Stack-Trace, bevor die NestedServletException geworfen wurde:

at com.kartuku.voucherweb.dto.PagedResponseDto.of(PagedResponseDto.java:29) 

Debug Ihren Test und überprüfen Sie die Werte in Ihrem Code.

Sie müssen entweder CompanyService und den Aufruf von CompanyService.find (...) (mit etwas wie Mockito) angemessen vortäuschen oder irgendwie eine tatsächliche Instanz von CompanyService bereitstellen.
